LAUNDRY DRIER.

Application filed July 24,

To all whom it may concern:

Be it known that I, BERT C. BAKER, a citizen of the United States, and a resident of Prairie Depot, in the county of lVood and State of Ohio, have invented a new and useful Laundry Drier, which invention is fully described in the following specification.

My invention has for its object to provide a simple and efiicient domestic laundry drier that may be used for rapidly drying fabrics. The drier is designed to receive the ordinary wash tube size or amount of clothing when they have been cleansed and dry it while any succeeding lot of clothing is being washed or cleansed. By this means the cleansing and drying of the clothes may be completed in a continuous operation so that laundrying may rapidly be done without the necessity of waiting for clothes to be dried on the line, as is commonly done.

Thus the invention has for its object to produce a machine that may be used by anyone for the purpose of drying clothes. The invention provides a simple means for directing heated air over and through the clothes as they are being tumbled by suitable tumbling cylinders. The invention also has for its object to provide a plurality of cylinders that may receive successive wash-tub amounts of clothing. which may be found desirable where the drying of each batch of clothes cannbt becom-pleted while a single batch of clothes is being cleansed. The invention also has for its object to produce other advantages and to provide other features which will appear from the following description and upon examination of the drawings.

The invention may be contained in structures that diifer in their details and still be within the purview of the novelty of my invention. In order that a practical application of the invention may be described, I have selected two structures as examples of structures containing my invention and shall describe them hereinafter. The structures selected are shown in the accompanying drawings.

1824. Serial No. 727,863.

Figure 1 .is a side view of a part and a sectional view of another part of one of the laundry drying machines selected for purposes to illustrate practical application of my invention. Fig. 2 is a vertical sectional view of one end of the machine shown in Fig. 1. Fig. 3 is an end view of the machine, a part being shown bro-ken away. Fig. 4 is a top view of the machine. Fig. 5 is a front viewof a modification of the machine shown in Fig. 1. Fig. 6 is an end view of the machine shown in Fig. 5.

The machine is provided with an outer shell or case 1 which is supported on suitable legs 2. A pair of rotatable drums 3 and 4 are pivotally supported within the shell 1. The shell or case 1 is provided with the doors 27 and the drums 3 and 4 are provided with doors 5 whereby clothes may be inserted within and withdrawn fro-m the drums 3 and 4. The case 1 may be formed of sheet metal and the sides of the drums 3 and 4 are formed of reticulated material such as wire fabric, while the end walls of the drums may be formed of sheet metal 7. The ends of the drums may be strengthened by suitable spiders 8 'and the walls may be provided with the ribs 45 formed of wood. The ribs 45 are located on the inside of the wire fabric 6 and will co-act to cause the clothes to tumble as the drums are rotated. The drums are rotatably supported by stub axles 47 located at their ends and bearing members 10 are supported on the case 1. The outer stub axles 47 are connected to drive wheels 11. The drive wheels 11 may be grooved wheels that are driven by the'belts 12. Small grooved wheels'13 are rotatably supported on a shaft 14 that 1S!1I1 turn rotatably supported on the ends of the case 1 and clutch members 15 may be operated to connect the shaft 14 with the drums 3 and 4. A wheel 17 is connected tothe shaft 14 and is connected by a belt to a wheel 18 that is driven by the motor 19. Thus the shaft 14 is driven by the motor 19. When it 1s desired to connect the drum 3 with the rotating shaft 14 it may be done by shifting the clutch member 15 and the wheel 17, and

when it is desired to connect the drum 4 with the rotating shaft 14 a similar clutch at the other end may be thrown. Thus both drums may be connected through the shaft 14 and driven by the motor 19. When,

v hpwever it is desired to stop the operation either drum, it may be done by opening one or the other of the clutches. Clothes may\then be Withdrawn from or inserted in the drum that has been disconnected. After a new lot of clothes has been inserted in the drum the clutch controlling that drum may be operated and the drum started in its roments 24 may be located and which are contumbled by the drums.

nected to an external circuit by means of wires 25. As the air strikes the pan 23 it is. spread laterally and the air passes over the electrical heat unit-s 24v and is then deflected upwards by the obliquely arranged sides 48 towards the drums. The air may be heated by any suitable form of heater, such as by heating the pan 23 by gas or gasoline or other form of fuel, and deflecting it to the drums by the pan. The heated air passes through the sides of the drums and against the clothes and escapes by a flue 26 that may be connected with the chimney or a vent leading to a point'outside of the house or building. Thus the air circulates downward through the flue 22 and is heated by the electrical heat units 24 and is then deflected upwards to the clothes, as they are being Thus the contact with the rapidly moving air not only dries the clothes, but inasmuch as .a large quantity of air is directed against the clothes in a very short interval, the oxygen of the air to a large extent purifies the clothes and disinfects them as the drying progresses.

In the form of construction illustrated in Figs. 5 and 6 a single drum 30 may be used that is similar in construction to the drums 3 and 4. It .is located in a case 31 also similar to the construction of the case 1 shown in Fig. 1. It is rotatably supported on the stub axles 36. The drum 30 is driven by a motor 32 which is connected by means of a belt 33 and pulley wheel 34 to one of the stub axles 36. The case 1 is provided with a door 37 and the drum 30 is provided with a door 38, whereby the interior of the drum is renderedv accessible and the clothes inserted or withdrawn from the cylinder. blower 46 is located on top of the shell 31 to prevent short circuiting of the air froin' the opening 39 to the flue 40. The end portions 'of the plate 41.are turned rearwardly to form a short downwardly extending flue. A diverting or deflecting plate 42 is also located at the rear of the case 31 and just below the plate 41. The deflecting plate 42 has a portion 43 that is curved away from the curvedwall so as to direct a major portion of the air forward to the lower side of the drum. The drum is rotated counter clockwise, looking in the direction indicated in Fig. 6, so as to bring the tumbling clothes in proximity to the deflecting plate 43 and so that the falling clothes will receive the full benefit of the air entering through the opening 39.

The deflecting plate 42 is provided with a plurality of electrical heat elements 44 having a suitable resistance wire that is connected to a source of an electric current. The air will pass over the heated elements and will become heated and will be deflected to the drum by the deflector plate. Thus the air will dry the clothes by reason of its rapid movement over and through the cloth 1n of; flue'40, and if desired, out of the build ing.

' I claim:

The moist air will pass out through a case for containing and rotatably supportcirculate through the drum, a deflecting plate for deflecting the air towards the drum to cause the air tocirculate through all parts of the drum, electrical heat elements located on the deflecting plate for heating the air as it is being deflected by the deflecting plate.

2. In a laundry drying machine, a case, a pair of reticulated drums rotatably supported in the case, a flue extending downward between the adjacent ends of the drums, a blower for causing air to move down and through the flue, a deflecting plate for deflecting the air tothe drums.
